Disadvantages:

First, the elderly need to do what they can to climb the mountain and avoid overload exercise. Old people's health is declining. Mountaineering consumes a lot of energy and is an activity that requires physical strength.

Second, elderly people with cardiovascular and cerebrovascular diseases should be accompanied when climbing mountains. Older people with these diseases should not exercise excessively. They should exercise with their family and friends, and they should always have medicines ready for emergencies.

Third: diabetic patients should be alert to hypoglycemia. Mountaineering helps diabetics to control their weight and lower their blood sugar, but they should also be especially careful to prevent hypoglycemia. Such patients should eat less food before climbing or start climbing an hour after meals.

Fourth, elderly people with osteoarthrosis should avoid climbing mountains. People's knees are often in a semi-flexion state, and climbing mountains is very laborious, which will cause great wear and tear on the knee joint.
